Command Columns

Command columns are used for interaction. The TreeList provides the following command columns.

Editing Column
Contains editing controls. Appears when editing is allowed and depends on the editing mode.

Adaptive Column
Contains buttons that expand adaptive detail rows. Appears if columnHidingEnabled is true or hidingPriority is set for at least one column and only when certain columns do not fit into the screen or container size.

You can also customize cells of command columns using the onCellPrepared function. To distinguish cells of a command column from others, check the argument's column.command field for the "edit" or "adaptive" value.
